Hi. I'd actually leave the FF in for a bit longer. Only a few hardcore guys here still dump the FF that early. Bascily, the filter catches EVERYTHING the engine might shed, plus the oil contains extra moly and other break-in specific additives. Moly helps the cyl cross-hatching wear flat rather than being rolled-over. That being said, you are in Anchorage, lol. To answer your question, once you change the FF, don't worry about the base oil. If the oil has plenty of moly, that would be a plus. I can't say which synth oil up there has moly, but Esso XD-3 is a great choice if you can get it. I'd totally skip the semiblend oil for full synth considering your location and coming into winter....the semiblend being sort of a half-measure.
Personallty, I use a bit of 2-cycle oil in the gas and did so for break-in, which could also be a nice addition in super-cold starts. imo, your break-in will be fine no matter what you do, just leave the FF in as long as possible and go strait to synth. Look in to a synth with moly, if you want to optimise.
